What travelers say about TailSim

Business trip to Lisbon

I bought the eSIM the night before my flight and it was already installed when I landed in Lisbon. Coverage held in the metro and out to Belém, and the support chat answered within a couple of minutes when I wasn't sure which plan covered the tram.

Amara O. Nigeria

Two weeks in Peru

I travelled through Lima, Cusco and Machu Picchu with a single eSIM. The signal was good in the cities and in the Sacred Valley; the only place I struggled was deep on the mountain trail, but the hostel staff had told us not to expect much there anyway.

Tomás R. Chile

Solo trip to Tokyo

I have paid for roaming in Japan three times and it always cost me a fortune. This time I kept my own number, the data just worked from Narita, and I could use the transit app the whole week without hunting for a pocket Wi-Fi.

Hiroko N. Japan

Family trip to Spain

We travelled with two kids and their tablets, which is exactly where roaming normally falls apart. The eSIM let all five of us connect at once on the Costa Brava, and setting it up on the kids' phones took less time than finding the paper vouchers in my bag.

Ingrid H. Norway

Road trip through South Africa

Cape Town to Durban by car using the 10-day plan. It held up in Johannesburg and along the coast. I lost signal twice in the Karoo, exactly where my own phone does too, so I cannot blame the eSIM for that.

Kwame A. Ghana

Digital nomad month in Mexico

A full month working from Mexico City and Oaxaca. I split data between the laptop and the phone without counting minutes, and the plan did not run out before the end of the month. Video calls from a terrace in Roma Norte stayed stable all morning.

Sofía R. Mexico

City break in Barcelona

Four days in Barcelona, mostly maps and photos. The connection never dropped and I never had to look for a shop selling tourist SIM cards. For a trip that short I would have liked a cheaper smaller plan, but the experience was faultless.

Lars E. Denmark

Honeymoon in the Maldives

We spent a week in the Maldives and I was nervous about coverage on a small island. It worked at the resort, it worked in Male, and it kept the map running during the boat trip to the atolls. Worth it for the peace of mind alone.

Mei L. Malaysia

Conference trip to Berlin

Three days of conferences in Berlin, so I needed data in the halls and at the station. The eSIM held a connection the whole time. The only snag was that I had to re-scan the QR code after a system update mid-trip, and the support email walked me through it.

Andrei P. Romania

Two weeks in Colombia

Medellin, Bogota and the Caribbean coast with one eSIM. Coverage in Bogota was excellent, decent in the coffee region, and steady on the beaches. Support answered me in Spanish on WhatsApp, which was a pleasant surprise.

Diego M. Argentina

Family trip to Thailand

We flew into Bangkok and drove north to Chiang Mai with two data-hungry teenagers. The 15-day plan covered all of it, including the week we spent in Pai, and the connection was fast enough for them to stream on the long drives.

Yuki S. South Korea

Business trip to Turkey

Two weeks in Istanbul and Ankara for work. The eSIM activated instantly and never let me down in the meetings that mattered. Coverage in a couple of the smaller towns was weaker, but that has been true of every carrier I have used there.

Fatima Z. Pakistan

Ski trip to the French Alps

Ten days in the French Alps. The eSIM was the only thing that worked at altitude for me, and I could check the lift status and my messages without walking back to the chalet. It also meant nobody at the desk had to sell me a physical SIM.

Oliver B. United Kingdom

A month across South America

Four countries on one eSIM for the month: Peru, Bolivia, Chile and Argentina. The activation instructions were in plain language, and the coverage held up even around Salar de Uyuni, which I did not expect at that altitude.

Beatriz A. Brazil

Business trip to Singapore

A week in Singapore for meetings, and the eSIM was running before the taxi reached the hotel. Speeds were excellent in the CBD. I only wish the plan names made it clearer which one covered my data needs; I had to ask support to point me to the right one.

Ravi N. India

Two weeks in Italy

Rome, Florence and a week in the Cinque Terre on foot. Maps, train tickets and a lot of walking every single day, and the eSIM never dropped once. I have not carried a physical SIM since that trip.

Marta K. Poland

Ring road in Iceland

Around Iceland on the 10-day plan. It worked in Reykjavik and along the south coast; we lost signal in the highlands, which the rental company also warned us about. Maps and the booking app never stopped working, which was the part that mattered.

David O. United States

Five days in Morocco

Marrakech and Essaouira for five days. I activated the eSIM while waiting at the gate and by the time we landed everything was set up. It made the medina days much easier, because I could use the map without burning through roaming data.

Nadia S. Morocco

Road trip through Portugal

The eSIM worked fine, I was just not ready for how much data the maps in the Douro valley use. Support added another 5 GB in a few minutes when I wrote in, which saved the last two days of the trip.

Elena D. Portugal

Remote work in the Dominican Republic

Two weeks working from Santo Domingo and Punta Cana. The connection in the hotel was fine and the beach wifi was the only weak spot, but my phone stayed solid throughout. Support answered in Spanish when I asked about topping up data mid-trip.

Carlos D. Dominican Republic

Backpacking Through United States

Backpacking through New York and Central Park was my morning escape. Jogged around the reservoir and found an outdoor chess game near the fountain. Used my phone to navigate the Subway and find cheap eats in Harlem. The data connection was perfect for sharing travel updates with family.

One-Week Trip to Miami

Educational trip to Miami focused on architecture. The Art Deco District is a living museum of 1920s design. Used my phone to research each building's history and found an amazing Cuban café nearby. The data connection was perfect for coordinating with my study group.

Group Trip to Mexico City

Coyoacán with friends on a Saturday - the market was insane. The Frida Kahlo museum line was too long so we skipped it. Grabbed tostadas at a street stall nearby, lived for the rest of the day.

Last-Minute Trip to Mexico City

Last minute trip to the Zócalo - the Cathedral at night is different. Had no plan so just walked around. Found this incredible pozole place two blocks from the plaza. Will dream about that broth.

Adventure Trip to Toronto

The dinosaur wing at the ROM was honestly better than I expected - spent two hours there. Phone worked fine for checking museum hours.

Family Vacation in Vancouver

Granville Island market was the highlight - the fresh bread situation is no joke. Pulled up their website to check the day's events before heading out.

Living in United Kingdom

Living in London as an expat and visited Buckingham Palace on a sunny afternoon. The changing of the guard is iconic - checked the schedule on my phone first. Found a great gastropub in Camden using my data connection. The mobile coverage throughout was flawless.

Pilgrimage to London

Spiritual retreat in London with a visit to Hyde Park. The park is massive and peaceful - used Google Maps to find the Peter Pan statue. Took the River Bus back to Westminster for amazing Thames views. Data worked perfectly on the boat.

Road Trip Through Spain

Road trip from Lisbon to Madrid - arrived at Sol hungry and found an amazing churros spot using my phone. The famous clock tower is right there and the energy of the city is contagious. Great stop on any Spain itinerary.

Short Trip to Madrid

Food tour of Madrid - used my phone to find the best tapas bars along Gran Via. Found a hidden gem near Plaza Mayor that wasn't in any guidebook. The data connection was perfect for translating menus and checking reviews.

First-Time Visitor in Rome

First trip to Europe and the Vatican Museums left me speechless. The Sistine Chapel ceiling is even more stunning in person. Used my phone for audio guide navigation and to find a nearby pizzeria afterward. The data connection worked perfectly throughout my first-time traveler experience.

Long Stay in Milan

Spiritual retreat in Milan with a day to explore the Galleria. The architecture beneath the glass cupola is breathtaking. Found a quiet church nearby for reflection. My eSIM was helpful for finding wellness centers and healthy restaurants in the city.

Short Trip to Lyon

Spent hours exploring Vieux Lyon - the traboules are fascinating. Found great silk shops and local boutiques. Used my phone to navigate the narrow streets and translate menu items. The Renaissance architecture is stunning.

Remote Work in Paris

Took a break from work to visit Notre-Dame. The rebuild is remarkable. Found a quiet bookshop nearby and spent an hour reading. Used my eSIM to check emails and coordinate with my team back home. Peaceful afternoon.

Honeymoon in Tokyo

Luxury trip to Japan and Tokyo Tower at night was exactly what I imagined. Grabbed a fancy dinner in Ginza after, found the restaurant through my phone. Service was impeccable. The 5G connection worked perfectly everywhere I went.

One-Week Trip to Kyoto

School trip to Japan and Arashiyama bamboo grove was the cover photo moment of the whole tour. The rustling bamboo, the temples nearby. Used Google Translate to chat with a local monk about the history. Unforgettable.

Family Vacation in Athens

Multi-generational trip and the Temple of Olympian Zeus blew everyone away - those columns are massive. Took the bus back to Plaka, my kids loved the gelato shop on the corner.

Family Vacation in Santorini

Red Beach with the family - the red sand and turquoise water is unlike anything. My kids collected volcanic rocks while I relaxed. Grabbed fresh fish at a taverna nearby. Perfect day.

Digital Nomad in Berlin

Digital nomad working from Berlin - visited the Holocaust Memorial for contemplation. The concrete stelae are powerfully moving. Found a great coworking cafe nearby using my phone. The 5G connection was fast for video calls.

First-Time Visitor in Munich

First time in Germany and the BMW Museum in Munich blew my mind. The history of automotive engineering is fascinating - used my phone to translate exhibit descriptions. Found the Augustiner beer garden nearby. Data connection never dropped.

Remote Work in Sydney

Took a week off and barely checked email, but I did use the data for Google Maps and WhatsApp with my partner back home. Coverage around the harbour was strong even during the fireworks. Felt disconnected from work but very connected to the city.

Family Vacation in Melbourne

My grandmother wanted to see this building since her childhood. The audio guide app worked perfectly inside - we didn't have to queue for a physical device. Took dozens of family photos and shared them with relatives in Japan through WhatsApp without lag.

Business Trip to Chiang Mai

Business trip to Chiang Mai with a free evening for the Night Safari. The nocturnal animals and Safari Park tour was incredible. Found a quiet restaurant near the old city using my phone. My eSIM made it easy to coordinate with colleagues back home.

Family Vacation in Bangkok

Family trip to Bangkok and Chatuchak Weekend Market was incredible. Found amazing Thai crafts and the kids loved the pet section. Used my phone to find the best mango sticky rice vendors. The SkyTrain made it easy to get there without traffic.

Family Vacation in Rio de Janeiro

Spent four days near Posto 6 with the kids. 4G was solid along the boardwalk, slow only in the older kiosk at the far end. Uber pickups were fast and the driver got us in under three minutes every time.

Solo Trip to Rio de Janeiro

Took the van up to Corcovado at 7am to beat the crowds. Mobile data worked in the ticket line and at the summit, so I could send the photos back home without waiting. The 5G stayed stable even with a few hundred people around the platform.

Digital Nomad in Amsterdam

Leidseplein for a quick coffee break - the square has good energy. Found a quiet coworking spot nearby through a local Slack channel. WiFi there was decent.

Transit Through Netherlands

Anne Frank House was heavier than expected - the hidden rooms are small and the atmosphere is haunting. Booked tickets months ahead which was lucky. Data worked fine.

Group Trip to Busan

Group trip to Busan and Gamcheon Village was a highlight - the colorful houses and murals are incredible. Found a hidden café with amazing views through my phone. The 5G connection was solid.

Short Trip to Seoul

Shopping trip to Seoul and Gyeongbokgung Palace was incredible - the Joseon dynasty architecture is stunning. Rented a hanbok and took photos everywhere. Connection worked for sharing in real time.
